Results show that the combined technique compresses the dynamic range of submarine signal effectively and meets the demand of shallow sea dynamic range for the airborne laser bathymetry.

试验结果表明，多种方法相结合的技术可对水底信号的动态范围进行有效压缩，满足机载测深系统对浅海测量的动态范围要求；但正交偏振技术对信号测量压缩的改善效果并不明显。

Many industries use helically and spirally coiled heat exchanger tubes for single-phase, evaporating, and condensing flows.

在很多工业领域中，螺旋管式热交换器都得到广泛的应用，它可适用于单相流体、蒸汽以及可压缩流体的流动。

However, in electric field computation, the BEM has not much unfould and most of them are limited in the conventional BEM. In the flow field computation, although some achievements have been gained in solving the constant and uncompressible fluid flow by using BEM, but to the inconstant, compressible, nonlinear, transonic flow, such as the flow in the arc quenching chamber in SF6 high voltage circuit breaker, no any report has been published up to now for the reason that the basic solution of this kind of flow has not been found.

目前，在电场计算领域所开展的工作相对较少，而且仅限于传统边界元方法的应用；在计算流体力学领域，近年来虽然一些学者应用边界元法，在解决定常、不可压缩等问题进行了相当深入的研究，获得了若干研究成果，但是对于像SF_6高压断路器灭弧室中存在的非定常、可压缩、非线性、跨音速、具有复杂而且变边界的气流场由于至今尚未找到基本解，而未见研究工作的报道。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
